Why we picked it
The single best thing ever written on customer conversations. It teaches you to ask about the customer's life and past behaviour, not your idea, so you can't be lied to. If a founder reads one thing before talking to a single customer, it's this.

- Talk about their life, not your idea.
- Ask about specifics in the past, not opinions about the future.
- 'That's so cool, I'd totally buy it' is a compliment, not data, dig for commitment and evidence.

Why we picked it
The free, original essay that defined the MVP before the book existed, written plainly by the person who coined the term. It clears up the most common mistake founders make, which is thinking an MVP has to be a working product when a landing page or a video often teaches you more, faster. Useful as a quick primer you can send someone in one link.

- An MVP is the smallest thing that produces validated learning, not the smallest product
- A page or a video can be a legitimate MVP if it tests real demand
- Aim for maximum learning per unit of effort, not feature completeness

The canonical fake-door test, told by the founder who ran it. Buffer started as a two-page site: one page pitched the tool, a pricing button led to an email capture, and every signup got a personal note. Real demand, real conversations, a paying customer in weeks, and not a line of product code.

- Test willingness to pay with a pricing page before you build.
- Email every signup by hand and start a conversation.
- A landing page measures behaviour, not opinions.

Todd Jackson studied how dozens of now-large companies validated their very first idea. The pattern that repeats: deliver the outcome by hand, talk to real users, and watch for genuine emotion. A polite 'that's cool' is a no. Strong reactions are the signal you want.

A clean, practical playbook for the mechanics: where to place the door, what to measure, and how to avoid annoying the people who walk through it. It covers the in product version (a button for a feature you have not built) alongside the standalone landing page, so you see both shapes of the test. Good for turning the concept into a concrete plan you can ship this week.

- The door can be a button inside an existing product, not only a new page
- Decide your success metric and sample size before you launch
- Show a graceful coming soon message so testers do not feel tricked

Why we picked it
This is the most concrete walkthrough of how to test a niche when you have nothing built yet: put up a page describing the offer and count who actually clicks or signs up. It treats a click as a behavior, not an opinion, which is exactly the difference between real demand and polite interest. It gives you the seven steps, rough benchmarks, and the ethics of an honest reveal page, so you can run it this week for almost no money.

- A click or an email is a behavioral signal, worth far more than someone saying they like the idea
- Set your success threshold and sample size before you start, so you cannot rationalize a weak result
- Be honest on the reveal page ("coming soon, join the list") so the test does not burn trust in your own niche

A builder to builder account from someone who ran the test on their own idea, with the honest distinction that a landing page validates the idea, not the product. It is a useful reality check: signups prove interest in the promise, but you still have to prove you can deliver it. The comments thread adds real founders debating what a good conversion rate actually looks like.

A step by step for the exact test in the short answer: what the page needs (outcome, customer, problem, offer, call to action), how to drive a bit of targeted traffic, and what conversion tells you. It answers the practical questions a first timer hits, like how many visitors you need and what counts as a pass. A tidy how to you can follow start to finish.

- A smoke test page needs a clear outcome, offer, and single call to action

GV's method for building a realistic facade and testing it with five target customers in a single week, which is the interview flavoured cousin of the fake door. Their fake it philosophy, a convincing front is all you need to learn, is the same principle as a landing page test applied face to face. Use it when you want qualitative reactions to a prototype alongside the quantitative click data.

A validation walkthrough written for the Indian context, covering landing pages, coming soon fake doors, and pre orders with tools and channels that make sense locally. It is a practical starting point if you want examples framed around Indian customers and spending behaviour rather than Silicon Valley defaults. Pair it with the deeper global pieces above for method.

The permission slip to recruit users by hand, do things manually, and deliver 'insanely great' experiences to your first few customers. The cheapest, most honest way to validate demand is to go get it one person at a time.

- Recruit your first users manually, don't wait for them to come.
- A tiny group of users who love you beats a big group who like you.

This is the founder essay that made the case for validating before you build, from the person who did it with Buffer. Gascoigne frames the no-code or landing page MVP not as a shortcut to a product, but as a way to learn whether anyone actually wants the thing, which is exactly the stance this question takes. His honest point is that 120 signups plus real conversations taught him more than any polished build would have.
From
Medium (Joel Gascoigne, co-founder of Buffer)
by Joel Gascoigne
- The goal of a no-code or landing page MVP is validated learning, not vanity signups: talk to the people who respond, do not just count emails.
- Anything can be your MVP as long as you are genuinely testing demand before committing to a full build.
- Buffer got only 120 signups in seven weeks, but the direct conversations proved real interest and led to paying customers at launch.
